TIE-PLATE WASHER,

Specification of Letters Patent.

lPatented Sept. 7, 1909.

Application led September 14, 1908. Serial No. 452,875.

To all fwhom it may concern: A

Be it known that I, JOHN W. KENDRICK, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Im rovementsin Tie-Plate Washers, of which t e following is a specification.

My invention relates to washers adapted to be used in connection with the flat metal plates which underlie the rails .where they are'` supported by the ties. In the past such tie plates have been made with square or rectangular holes, there being twosucli holes in each tie plate, one on either side of the rail adjacent to the base thereof. The ordinary (spikes having square cross' sections, were riven through these holes into the wooden tie, the heads of the spikes overhanging the edges of the rail base, and thus securing the rail down to the tie plate and the tie. I have found that it is desirable in many cases to useround screw spikes instead of the old square spikes. In some cases old ties can have the square spikes withdrawn, and can then be ada ted for use with the screw spikes. In other cases it may be desirable to use screw spikes with'new ties. In any such case the old tie platesare useless, unless they can be made over' and adapted to be used with screw s ikes;l

There are two respects in which the o d ytie plates are unsuitable for use with screw spikes, (1) the 's nare holes 4are too small to receive the roum, screw spikes, and (2) the head of the screw spike needs to, be supported on the side opposite 'to the edge of the rail base. I have invented a combination which adapts old tie plates to be used with screw spikes.

N,Referring to the accompanyingdraw- ,ings-Figure 1 is a cross section of a rail resting on a tie late, and showing two different forms o my improvement at the sides thereof. Fig. 2 is a top plan view corresponding to Fig. 1. Figs. 3 andfl are perspective views of the tie plate washers shown in Fig. 1. Fig. 5 is a top plan view of a4 third form of my invention. Fig. 6 is a perspective View of the same.

The rail 15 is shown with itsbase 16 rest'- ing upon the tie'plate 17. On one side, this tie plate is"shown as having a longitudinal ridge 18, which lits against L'the rail base 16, thus forming a seat on the tie plate 17 for the rail base. The tie late 17 has large round holes 19 punched t erein. In case an late is made over, these round holes 19 will be formed by punching out the original square holes for the square spikes.

The tie plate washer comprises a ring 20, having substantially the same thickness on one side as the tie plate 17, and adapted to litl into the hole 19. The hole 21 through the center of the rin 20 is adapted to receive the shaft 25 o the screw spike. On

one side of the ring 20 there is an offset 27v which hooks over the edge of the hole 19. Above the offset 27 is a concave shoulder 22 adapted to support the flaring head 24 of the screw spike. The ends of the odset 27 are indicated Ain Fig. 4 bythe reference nu-v A meral 23, land' they are adapted to rest against the rid- 'e 18 on the tie plate.

In the inodication shown in Fig. 3 and at the left of Figs. 1 and 2 the abutments 23a rest againstthe edge of the rail base 16, there being no guide ridge 18 in this case.,

In Figs.- 5 and 6I have shown still another modification having the holes 19EL in the tie plate 17 of- Square form. In this. case the part 20a which fits within the hole 19a is also square. There isan offset 27a similar to the oi'sets27 in the earlier described forms. It will be observed that in this modification the ends of the offset 27 do not necessarily abut against'the rail base 16 or the ridge 18,

this being unnecessary, beca-use the square tiorln of the washer prevents rotation and keeps it in place.

Of course, my inventionsis not. limited to use with old tie plates. WVhether the tie plates be'new or old the holes 19a can be punched in them, and in case the tie plates already have square holes for square spikes,

these can be punched out. In the case of the round holes in the tie plates rotation of the washer therein is prevented by the abutment's 23 '01 23l coming in contact with the ridge 18 or the Iedge of the rail base 16. It is to be noted that the rail base 16 overlies the edge of the ring 20 or 20, thus helping to hold it definitely in place. The concave shoulder 22 affords a seat to support the spike head 24 on the side thereof opposite 'to the rail base 16.

I claim:

:1. A tie plate washer comprising a part Too to fit. entirely around a spike within a hole in the tie plate, said parth'aving the same thickness as the tie plate on one side, and having an offset to overhang the opposite side ofsaid hole.

2. A tie plate Washer comprising a. ring adapted to t about a round spike within a hole in the tie plate, same thickness as the tie plate on one side but being thickened on the opposite side so as to form a shoulder to support the head of they spike.

3. In combination, a tie, a tie plate having Va holetherein, a ring in said hole, said ring havinga shoulder on one side overhai'iging Vthe ed' e of thel hole, and a spike extending throng said ring.

4. In combination, a tie plate havingl a hole therein', a ring within said hole, said ring being of the saine thickness on one side as the tie plate and having a projecting shoulder on the opposite side, and a spike through the ring having a head supported on one side by said shoulder.

5'. In combination, a tie plate, a rail thereon, said tie platel having a hole therein, a ring within said hole, the edge of' the rail bi-se overlapping` one edge of said ring, and an offset on the opposite edge of the ing.

6. In combination,s a tie plate' having a said ring having the vhead resting' on said shoulder hole therethrough`r a complete ring within said hole, a rail resting on the tie plate, :L projection lroni one side of said ring, and means to prevent rotation of the ring in the hole.

7. A tie plate washer comprising a part to lit around a spike within a hole in the tie plate, said part having the saine thickness as the tie plate on one side and having` a pro jecting shoulder on the shoulder having,r a concave seat to receive the head of a screw .spike and support the same.

S. In combination, a tie pla-te with a hole theretlirongh, a rail on the tie plate at one side of the hole', a washer Within the hole having a projecting shoulder opposite said rail, and a spike through the washer with its and also on the edge of the rail base.

ln testimony whereof, I have subscribed my naine.
